Spintronics in antiferromagnetic helix: A new prescription
Suparna Sarkar, Santanu K. Maiti
The occurrence of a finite mismatch between the up and down spin energy channels due to the application of an electric field, leading to the generation of a polarized spin current…
Circular currents in a magnetic ring with zero net magnetization in presence of a side-coupled one-dimensional chain
Sourav Karmakar, Suparna Sarkar, Santanu K. Maiti
We investigate persistent charge and spin currents in a magnetic quantum ring threaded by an Aharonov-Bohm flux, in the presence of a side-coupled one-dimensional non-magnetic chai…
Spin filtration in a single-stranded antiferromagnetic helix with slowly varying disorder: Higher order electron hopping
Suparna Sarkar, Santanu K. Maiti, David Laroze
This work explores spin filtration in a helical magnetic system within a tight-binding framework, where neighboring magnetic moments are aligned antiparallel. The helix experiences…
